OAK CREEK, Wisc. (CBS) -- Investigators in Wisconsin have interviewed more than 100 people as they try to piece together a motive for the mass killing at a Sikh temple outside Milwaukee. The shooter died at the scene and it now turns out he died by his own hand.
The suspect in the temple shooting near Milwaukee died from a self inflicted gunshot wound to the head. The FBI says Wade Michael Page turned his gun on himself after a police officer took him down with a shot in the stomach. Teresa Carlson, Special Agent in Charge with the Milwaukee FBI says, "I've seen the video, it is an amazing shot, and thank goodness."
Investigators say they have no evidence that anyone other than page was involved in the shooting at the Sikh temple in Oak Creek on Sunday. Despite evidence of page's connection to white supremacists, agents say at this point there is still no clear motive for the rampage. They're looking into more than 100 leads. Carlson says, "We are reviewing voluminous electronic records from Page's email accounts, his telephone. We're combing through dept of transportation traffic videos, and neighborhood security videos."
Investigators arrested page's former girlfriend misty cook over the weekend on a weapons charge. But the FBI says there's no sign she had anything to do with the attack.
Six people died in the shooting and four were injured. Three victims are still at this hospital, in the intensive care unit. One of them is Lt. Brian Murphy, who was shot at least eight times. The police chief says Murphy is improving fast. Chief John Edwards says, "He's up walking, they had him sitting up for a period of time. He's progressing amazingly."
The Sikh community is preparing for the first funerals on Friday. Members are asking for answers but without a living suspect, the FBI says they may never know what was in the shooter's mind.
Hundreds gathered in Oak Creek last night at a vigil for the victims.
